  It's always the same trade off: try to create a closer to lisp API vs. 
not getting to far away from the original one so the new API is easy to 
understand.

  The guys at pyopengl did a mirror of OpenGL. I don't know what should 
you do in lisp-gl, but for my graphical library I decided to diverge 
from the SDL lib. I'm sure someone will do an exact translation from 
SDL*.h with SWIG (or even manually)

  My idea is a library that can be used the following way:

(init :init-video)

(with-open-window (s "Hi, my window name is this" '(640  480) :doublebuf)
   (loop
    for i from 1 to 480
    do (draw-point s i i (random (expt 2 24))))
   (update s)
   (event-loop SDL_WaitEvent event
     (SDL_QUIT (quit))))

  I'm not interested in mimicking how the API works in C. If someone 
plans to work in lisp in a C way he can do it with the SWIG generated file.

  Some time in the future, when the low level SDL-cffi lisp file is 
stable I will base my library on top of it.
